[header] How to read your fingers [title] Measure the overall length. [step] The overall length of your fingers is measured relative to the size of your palm. On average, the longest finger is about seven-eighths the size of your palm. <sep> (A) Because of this, it is hard to read your hand's actual length. [substeps] If you have very long fingers, the curve of your fingers may be too small to be measured accurately. (B) Once you get to that length, you can see how the various finger shapes affect your reading. [substeps] Natural finger shapes are like feet or fingertips. (C) [substeps] For most basic haikus, keep a notepad nearby to record your measurement into your own writing. This helps provide a quick visual aid when you're waiting to read another line. (D) If it is as long as your palm, then your fingers are considered long. Short fingers are shorter than seven-eighths of the palm.
Output:
D
